Hi Vikram,
I am now looking at the android-omap-2.6.29 branch, and after having looked at the zoom2_defconfig file, I notice that power management is not enabled in the zoom2_defconfg file. Do you know if anyone managed to get a working PM implementation for android-2.6.29 for TI OMAP 3503/3430?
I adapted the zoom2 settings for my overo android-2.6.29 build, and find that the system doesn't go to suspend mode at all. :-)
So, while DSS2 and OMAP-PM have been integrated into the android-omap-2.6.29 branch, am I correct in concluding that power management suspend has not yet been implemented for android on TI OMAP 3503/3430?
For example, here is a snippet from the zoom2_defconfig that shows pm suspend not being enabled. Because of this android cannot suspend and blank the screen after a period of inactivity:

Even CPU power management is disabled:

# CONFIG_CPU_IDLE is not set
As you can see suspend is disabled.
